While many of the accounts removed last week appeared to originate from Iran, Twitter said this time that about 100 of the latest batch to be suspended claimed to be in the United States. Many of these were less than a year old and shared “divisive commentary.” These 100 accounts tweeted a total of 867 times and had 1,268 followers between them.

Since our initial suspensions last Tuesday, we have continued our investigation, further building our understanding of these networks. In addition, we suspended an additional 486 accounts for violating the policies outlined last week. This brings the total suspended to 770.

As examples of the “divisive commentary” tweeted, Twitter shared screenshots from several suspended accounts that showed anti-Trump rhetoric, counter to the conservative narrative that the platform unfairly targets Republican accounts.

Fewer than 100 of the 770 suspended accounts claimed to be located in the U.S. and many of these were sharing divisive social commentary. On average, these 100 Tweeted 867 times, were followed by 1, 268 accounts, and were less than a year old. Examples below. pic.twitter.com/LQhbvFjxSo

Twitter also said that the suspended accounts included one advertiser that spent $30 on Twitter ads last year, but added those ads did not target the U.S. and that the billing address was outside of Iran.

“As with prior investigations, we are committed to engaging with other companies and relevant law enforcement entities. Our goal is to assist investigations into these activities and where possible, we will provide the public with transparency and context on our efforts,” Twitter said on its Safety account.

After years of accusations that it doesn’t enforce its own policies about bullying, bots and other abuses, Twitter has taken a much harder line on problematic accounts in the past few months. Despite stalling user growth, especially in the United States, Twitter has been aggressively suspending accounts, including ones that were created by users to evade prior suspensions.

Twitter announced a drop of one million monthly users in the second quarter, causing investors to panic even though it posted a $100 million profit. In its earnings call, Twitter said that its efforts don’t impact user numbers because many of the “tens of millions” of removed accounts were too new or had been inactive for more than a month and were therefore not counted in active user numbers. The company did admit, however, that it’s anti-spam measures had caused it to lose three million monthly active users.

Whatever its impact on user numbers, Twitter’s anti-abuse measures may help it save face during a Senate Intelligence Committee hearing on September 5. Executives from Twitter, Facebook and Google are expected to be grilled by Sen. Mark Warner and other politicians about the use of their platforms by other countries to influence U.S. politics.
